Installing Linux, Apache, MySQL, PHP (LAMP) Manually
Before installing the software, update the information in the repositories using the following command.
root@i:~# apt-get update - for OS Debian, root@i:~# yum makecache - for OS CentOS
After the updates are completed, continue with the installation of the needed software.
Apache
OS Debian
Install Apache Prefork using the following command:
root@i:~# apt-get install apache2
Install Apache Worker using the command
root@i:~# apt-get install apache2-mpm-worker
For Apache ITK, use the following command:
root@i:~# apt-get install apache2-mpm-itk
OS CentOS
Install Apache Prefork using the following command:
root@i:~# yum install httpd
To update the version of Apache Worker, use the following command to stop the webserver:
/etc/init.d/httpd stop
Next, open /etc/sysconfig/httpd for editing and enable the HTTPD=/usr/sbin/httpd.worker line by removing the comment mark. If the following lines are not present in the file, add them:
<IfModule worker.c> StartServers 6 MinSpareServers 6 MaxSpareServers 15 ServerLimit 156 MaxClients 156 MaxRequestsPerChild 3000 </IfModule>
These directive values should be set as necessary.
To update the version of Apache ITK, enable the HTTPD=/usr/sbin/httpd.itk line by removing the comment mark. If the following lines are not present in the file, add them:
<IfModule itk.c> StartServers 6 MinSpareServers 6 MaxSpareServers 15 ServerLimit 156 MaxClients 156 MaxRequestsPerChild 3000 </IfModule>
These directive values should be set as necessary.
MySQL
OS Debian
To install a MySQL database server, use the following command:
root@i:~# apt-get install mysql-server mysql-client
During installation, you must enter the access password for the root user of the MySQL server. Use complex passwords that contain upper and lower case letters, numbers and special characters.
OS CentOS
To install a MySQL database server, use the following command:
root@i:~# yum install mysql-server mysql-client
When installation is complete, start MySQL using the command:
root@i:~# /etc/init.d/mysqld start
then change the password using the command:
root@i:~# /usr/bin/mysqladmin -u root password 'mynewpassword'
PHP
The following commands install the basic PHP extensions and a module for Apache.
OS Debian
To install PHP, run the command:
root@i:~# apt-get install php5 php5-mysql
OS CentOS
To install PHP, run the command:
root@i:~# yum install php php-mysql
Site
OS Debian
For each added domain, create a separate configuration file and name it for the domain:
touch /etc/apache2/sites-enabled/mydomain.com where “mydomain” is your domain name.
Open the configuration file to edit and add the following section:
<VirtualHost 1.0.0.1:80 >
ServerName mydomain.com
ServerAlias www.mydomain.com
DocumentRoot /var/www/sites/mydomain.com
CustomLog /var/www/httpd-logs/mydomain.com.access.log combined
ErrorLog /var/www/httpd-logs/mydomain.com.error.log
AddType application/x-httpd-php .php
</VirtualHost>
where 1.0.0.1 - is the server IP address and “mydomain.com” is your domain name.
If the website’s operation requires a database (MySQL in this example), connect to the server:
mysql -u root -p
and create a database:
create database db;
Create a user that will have full access rights to the database:
grant all privileges on mydb.* to 'myuser'@'localhost' identified by 'mypassword'; where “mydb” is the database name, “myuser” is the user name, and “mypassword” is the password.
Create directories for the site:
mkdir /var/www/sites/ mkdir /var/www/sites/mydomain.com mkdir /var/www/httpd-logs touch /var/www/httpd-logs/mydomain.com.access.log touch /var/www/httpd-logs/mydomain.com.error.log
If necessary, install the desired CMS by going to the site directory…
cd /var/www/sites/mydomain.com
For CMS Joomla, download its installation package:
wget http://joomlacode.org/gf/download/frsrelease/19639/159961/Joomla_3.3.2-Stable-Full_Package.zip
Unpack the .zip file using the command:
unzip Joomla_3.3.2-Stable-Full_Package.zip
With the correct DNS configuration, you will be able to access your site through a browser using its domain name; otherwise, you can use the IP-address.
OS CentOS
For each added domain, create a separate configuration file and name it for the domain.
touch /etc/httpd/sites-enabled/mydomain.com.conf where “mydomain” is your domain name.
Open the configuration file to edit and add the following section:
<VirtualHost 1.0.0.1:80 >
ServerName mydomain.com
ServerAlias www.mydomain.com
DocumentRoot /var/www/sites/mydomain.com
CustomLog /var/www/httpd-logs/mydomain.com.access.log combined
ErrorLog /var/www/httpd-logs/mydomain.com.error.log
AddType application/x-httpd-php .php
</VirtualHost>
where 1.0.0.1 -
is the server IP address and “mydomain.com” is your domain name.

mysql -u root -p
and create a database:

If necessary, set the desired CMS by going to the site directory…
cd /var/www/sites/mydomain.com
